Savage x will not shift into second gear!

Hey guys I'm new to this forum, but not to rc's. I'm a regular on the traxxas forum and have over 1,200 posts there.
Anyways, the reason I joined this forum is because I cannot talk about my HPI savage there.
The problem is, it will not shift into second gear. I've tried everything. The slipper clutch is tight, the gear shift disk like thing in the tranny works good (The pad doesn't stick at all), engine clutch shoes are good...brake is not dragging...I just cannot understand why this thing will not shift into second gear. The engine runs perfect, starts every time like nothing.
I was just driving it and it was working great...shifting and downshifting exactly as it should...then all of a sudden it just plain stopped shifting...it just revs up in first gear.
And I have tried adjusting the screws in the shifter in the tranny, going by what it says in the manual and turning it out (loosening it) so it will shift sooner.
No luck...no matter how far I turn it out it just will not shift.
I'm getting pretty aggravated...can you guys help me out here please? I'm relatively new to the savage and have only had it a few days. Maybe you guys with more experience with the truck can help.
